I just built a new linux box, and am fighting with details.
Mint Linux Cinnamon
.8.0-53-generic #56~16.04.1-Ubuntu SMP Tue May 16 01:18:56 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
GNU Image Manipulation Program version 2.8.16 (as per apt-get install)
When I try to use the gmic extract foreground tool I get an error. A youtube tutorial said to set the output mode to “new active layers” but that didn’t solve it.
The error dialog I see says something like:
error in gimp extract foreground command -f undefined variable I in expression V=I
